TEMPLE AND SPRING-CLAMP FOR LENSES OR THE LIKE- SPECIFICATION forming part of Letters Patent N 0. 718,363, dated January 13, 1903.

Application filed April 30, 1902.

I9 all whom it may concern..-

Be itknown thatLEMIL L. LEMBKE,a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Temple and Spring- Clamp for Lenses or the Like, of which the following is a full, clear, and exact description.

The invention relates to spectacles, eyeglasses, and like devices; and its object is to provide a new and improved temple and spring-clamp which is simple and durable in construction, cheap to manufacture, and arranged for convenient, quick, and secure attachment to or removal from a lens or like article without requiring apertures and bolts, pins, or similar fastening devices.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the im provement as applied to eyeglasses. Fig. 2 is an enlarged side elevation of the same. Fig. 3 is a plan view of the same, and Fig. 4 is a sectional rear elevation of the same on the line 4: at of Fig. 3.

The improved temple and spring-clamp is preferably made from a single piece of springwire formed into the front and rear clamping members A and B for clamping the corresponding faces of the lens 0 or other article on which the improvement is to be applied.

The front clamping member A is in the form of a loop inclosing a portion of the front face of the article at the outer side edge thereof, and the ends of the loop terminate in the connecting portions D D, extending around the edge of the lens and terminating in the loops B and B, which form the rear clamping member B, the said loops standing at right angles to the rear face of the lens approximately opposite the sides of the loop of the front clamping member A. Thus one arm of each loop B or B is in contact with the face of the lens, (see Fig. 3,) while the other arm is free of the lens-face, and one of the arms termi- Serial No. 105,363- (No model.)

mates in a coil E and the other in a pin F, extending into the central opening of the coil E. The latter extends in transverse alinement with the edge of the lens and between the outer ends of the two loops, and the said'coil terminates in the temple G.

Now by the arrangement described the entire device-that is, the temple and clampis made from one single piece of spring-wire, and the usual strain on the temple in the direction of its length causes a tightening of the spring clamping member B on the rear of the lens 0, and the temple is free to swing sidewise from the yielding coil with the latter as the fulcrum, so that the clamping members A and B are not liable to be pulled off the faces of the lens.

By having the rear clamping member in the form of loops standing at angles to the face of the lens the latter can easily be pushed in position between the clamping members A and B, as will be readily understood by reference to Fig. 3. The temple and its coil may be made in one or more pieces and the clamping members in a separate part, the coil being held on the pin F as the pivot for the temple to swing on.

By arranging the clamps on eyeglasses in the manner shown and described they occupy comparatively little room at the sides of the lenses, and hence are not in the least unsightly or cumbersome, but enhance the appearance of the eyeglasses.

Having thus described my invention, I

.claim as new and desire to secure by Letters engaging opposite .faces of the article, and a temple extending integrally from one of the clamping members, the outer end of the temple being one terminal of the wire,as set forth.

3. An attachment for lenses and like articles made of an integral piece of spring-wire and comprising front and rear clamping members, and a temple having an integral coil connection with one of the clamping members, the outer end of the temple being one terminal of the Wire, as set forth.

4. A spring-clamp for lenses and like articles, made of an integral piece of spring-wire and comprising front and rear clamping members, of .Which the front clamping member consists of an open loop lying flat on the front face of the article and the other clamping member consists of spaced loops standing at angles to the rear face of the article, connections between the loop of the front member and the loops of the rear member, in combination with a temple having a coil on the end of one of the loops of the rear member, as set forth.

5. A spring-clamp for lenses and like articles, made of an integral piece of spring-wire and comprising front and rearclamping members, of which the front clamping member consists of an open loop lying flat on the front face of the article and the other clamping member consists of spaced loops standing at angles to the rear face of the article, connections between the loop of the front member in combination with the loops of the rear member, a temple having a coil on the end of one of the loops of the rear member, and a pin on the other loop of the rear member, extending into the said coil, as set forth.

6. An attachment for lenses and like articles made of an integral piece of spring-wire, and comprising connected front and rear clamping members for engaging opposite faces of the article near one edge thereof, a temple having at its outer end one terminal of the wire and terminating at its inner end in one end of a coil having its other end integrally connected with one end ofthe rear clamping member, as set forth.

7. An attachment for lenses and like articles made of an integral piece of spring-wire, and comprising connected front and rear clamping members for engaging opposite faces of the article near one edge thereof, a temple having at its outer end one terminal of the wire and terminating at its inner end in one end of a coil having its other end integrally connected with one end of the rear clamping member, the other end of the rear loop terminating in a pin extending into the coil, the pin being the other extremity of the wire, as set forth.

8. An attachment for lenses and like articles made of an integral piece of wire, and comprising connected front and rear clamping members engaging opposite face portions of the lens adjacent to the edge thereof, in combination with a spring-wire temple on the rear clamping member, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EMIL L. LEMBKE.
